본 발명은 배터리 어셈블리 및 이를 포함하는 배터리 팩 및 자동차에 관한 것으로서, 더 상세하게는, CTP(Cell To Pack) 방식으로 제조되는 배터리 팩에 적용 가능한 배터리 어셈블리 및 이를 포함하는 배터리 팩 및 자동차에 관한 것이다.The present invention relates to a battery assembly, a battery pack including the same, and a vehicle. More specifically, it relates to a battery assembly applicable to a battery pack manufactured by the CTP (Cell To Pack) method, and a battery pack and a vehicle including the same. .
일반적으로, 이차전지(secondary battery)는 리튬 이온 배터리, 리튬 폴리머 배터리, 니켈 카드뮴 배터리, 니켈 수소 배터리, 니켈 아연 배터리 등과 같이 반복적 충·방전이 가능한 배터리를 말한다. 이러한 이차전지의 충·방전 기본 단위에 해당하는 배터리 셀(battery cell)의 출력 전압은 대략 2.5V에서 4.2V 정도이다.Generally, secondary batteries refer to batteries that can be repeatedly charged and discharged, such as lithium-ion batteries, lithium polymer batteries, nickel-cadmium batteries, nickel-hydrogen batteries, and nickel-zinc batteries. The output voltage of the battery cell, which is the basic unit of charging and discharging of these secondary batteries, is approximately 2.5V to 4.2V.
최근, 이차전지가 전기 차량(electric vehicle)이나 ESS(Energy Storage System) 등과 같이 높은 출력 전압과 대량의 충전 용량을 요구하는 장치들에 적용되면서, 복수의 배터리 셀을 직렬 또는 병렬로 연결하여 배터리 모듈(battery module)을 구성하고, 이와 같이 구성된 다수의 배터리 모듈들을 다시 직렬 또는 병렬로 연결하는 방식으로 제조되는 배터리 팩(battery pack)이 널리 사용되고 있다.Recently, secondary batteries have been applied to devices that require high output voltage and large charging capacity, such as electric vehicles or ESS (Energy Storage Systems), and multiple battery cells are connected in series or parallel to form battery modules. Battery packs, which are manufactured by forming a battery module and connecting a plurality of battery modules thus configured in series or parallel, are widely used.
그러나, 한국 등록특허공보 제10-2379227호, 한국 공개특허공보 제10-2022-0052183호 등에 개시된 바와 같이, 기존 기술은 배터리 셀들을 박스 형태의 금속 케이스에 수용하여 배터리 모듈을 구성하고, 이러한 배터리 모듈들을 다시 배터리 팩 케이스에 수용하는 방식으로 배터리 팩을 제조하기 때문에, 전체 배터리 팩의 무게와 부피를 증가시키고 배터리 팩의 에너지 밀도를 떨어뜨리는 문제점이 있다.However, as disclosed in Korean Patent Publication No. 10-2379227, Korean Patent Publication No. 10-2022-0052183, etc., the existing technology constructs a battery module by housing battery cells in a box-shaped metal case, and these batteries Since the battery pack is manufactured by housing the modules back in the battery pack case, there is a problem that the weight and volume of the entire battery pack increases and the energy density of the battery pack decreases.
반면, 배터리 팩의 에너지 밀도를 높이기 위해, 다수의 배터리 셀들을 배터리 팩의 케이스에 바로 장착하는 기존의 CTP(Cell To Pack) 방식이 적용되는 경우, 다수의 배터리 셀을 동시에 취급하기 어렵고, 그 장착 과정에서 배터리 셀들의 손상이 발생할 위험이 있다. 더욱이, 기존의 CTP 방식은 배터리 셀 장착용 구조체들이 케이스 내에 중복적으로 배치되어 배터리 팩의 무게와 부피를 경감하는 효과가 떨어지고, 제조 비용이 증가되는 문제점이 있다.On the other hand, in order to increase the energy density of the battery pack, when the existing CTP (Cell To Pack) method of installing multiple battery cells directly into the battery pack case is applied, it is difficult to handle multiple battery cells simultaneously and their installation is difficult. There is a risk of damage to the battery cells in the process. Moreover, the existing CTP method has the problem of reducing the effect of reducing the weight and volume of the battery pack and increasing manufacturing costs because the battery cell mounting structures are arranged redundantly within the case.
